This is a Margaret Howell shirt from the 2020SS collection. It's an open-collar shirt made with a lustrous, thin cotton poplin material, and while it has work details, it's designed to look refined. Although it's shirt fabric, it doesn't have cuffs. The boxy cut, double stitching, large four buttons, and a slightly forward-angled, three-dimensional sleeve construction combine to give it an outerwear-like feel. I think it would be cute to wear a thin shirt underneath when it's chilly. The color is khaki, the size is L, and it's 100% cotton. It's khaki and has work details, but it leans slightly towards a mid-tone, and the material is very elegant, so it doesn't have much of a military-like ruggedness. It's only been worn a few times, and there are no noticeable stains on the collar or sleeves, so it's in very clean condition. It's an item that can be worn year-round. If you're looking for one, please consider it.
